All Motorola Moto X models get unofficial Stagefright fix: How to install

All Moto X device owners can now install the unofficial stagefright fix on their smartphone via modified Brazilian OTA firmware, with due credit to XDA Developers' senior member, mastarifla, who has created new library files with the patch for the latest Brazilian OTA. Furthermore, the modified firmware has been tested and confirmed to work fine on T-Mobile variant of Moto X.

As mastarifla reports in his recent post on XDA forum, the library files have not been tested with KitKat. Hence, you need a Moto X running on Android 5.1 Lollipop for this fix to work properly.

Here is the complete step-by-step guide to install the Stagefright fix on your Moto X:

Ensure that your Moto X is rooted

Take a backup of the stagefright files (30 total) to a safe location on your phone's SD card
